DISPENSING TOP FOR CONTAINER-S.

Application filed April 19, 1924. Serial No. 707,601.

To all whom, it may concern:

Be it known that I, DANIEL W. LAYMAN, a citizen of the United States,and a resident of Indianapolis, county of Marion, and State of Indiana,have invented a certain new and useful Dispensing Top for Gontainers;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,in which like numerals refer to like parts.

This invention pertainsto a. dis ensing cap or top for containers, andparticularly for use on collapsible tubes containing paste or the like,but which may also be readily adapted for use on cans or similar tubesof paste or powder containers.

The object of the invention is to provide a sliding member forcontrolling the orifice through which the material may be dispensed, insuch fashion that the usual type of screw cap will be avoided with theconsequent possibility of losin the same.

The principal feature of t e invention resides in the construction andmounting of the sliding valve or closure member on the top of thecontainer, wherein the maximum degree of eificiency and cheapness inconstruction may be obtained, and it may be readily assembled.

Another feature of the invention resides in the wedging arrangement ofthe dove-tail tongue and groove sliding joint, whereby the valve may beslightly wedged in closed position suficient to hold it againstaccidental opening. This also may be accom plished by roughening theengaging parts of the tongue and groove.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims:

In the drawings, Figure 1 is a plan view looking down on the top of thecontainer showing the valve closure in closing position. Fig. 2 is acentral vertical section through the top of the container showing thevalve closure in open position. Fi .3 is a section taken on the hue 3-3-of ig. 2. Fig. 4 is a side elevation of the top of the container. I y

In the drawings there is shown what may he a paste tube 10 or any othertype of container, such a box or can, having an annular metal top 11 ofreduced diameter and connected with the tube 10 by'the tapering ofconical neck portion 12. The top 11 is provided with a discharge opening13 provided with a slot 14. The exposed surface of the top 11 isprovided with a diametrically extending dove tailed groove 15 in whichis dove tailed, so as to be slidably mounted therein, a valve or closingmember 16. Said valve or closing member is provided with a transverseslot 17 adapted to register with the dispensing slot 14 when the valveis moved to one position, as shown in Fig. 2. When the valve is moved tothe position, as shown in Fig. 1, the slots 14 and 17 are out ofregistry so as to prevent the escaping or dispensing of the contents ofthe container.

The valve member is so arranged with respect to the top 11 that theupper surface of each of them are flush and in the same plane, the dovetailed tongue and groove the operation of the valveerably the endbearing the upright projection 18 so that upon closing the valve theremay be a sli ht wedging action which will frictionally old the valve inclosed position. In addition to the above-mentioned widened projection,there are oppositely disposed lateral projections 19 soarranged as toengage the adjacent side of the cap 11 for limiting the sliding movementof the valve to closed position. After the valve has been positionedwithin the top, the opposite end thereof from the projection 18, whichcomprises the tongue 20, is bent downwardly to provide a stop and limitthe movement of the valve in the opposite direction, as well as thethumb piece for pushing the valve into open position. After the tongue20 has been bent downwardly into as shown, it will be obvious that t evalve is located in slidable relation with the top 11 so that it cannotbe removed therefrom and will not disengage the same unless the tongue20 is again bent upwardly. Each sideof the annular cap 11 is providedwith a recess 21 for receiving the tongue 20, and

osi'tion,

into which said tone engages in limiting the movement of the valve,whereby said tongue, when in that position, will be within the peripheryof the top and out of the way.

Whereas the top is shown herein as being annular, it is obvious that itmay be square without efi'ecting this invention, and that the slots maybe of any desired shape or configuration. Furthermore, if desired,

1 there may be substituted for the upwardly extending projection or thefinger-hold 18, a downwardly extending tongue 20, as shown. Thisarrangement would provide a tongue 20 on both ends of the valve for T5limiting its sliding movement in both directions and retaining the valvein place.

The invention claimed is: A. dispensing device comprising a neck with adispensing outlet therethrough, a

flat top for said neck having an opening maaeea therein communicatingwith the interior of said neck,- the outer face ofsaid top having arelatively wide dovetailed groove extending entirely across the same, aplate slidable in said groove and having its outer face flush with thecorrespond ng face of the said top, widened portions at the edges ofsaid plate at one extreme end thereof to frictionally bind within saidgroove to positively limit the movement of the said plate in onedirection, and to frictionally hold the same against retraction, and thesaid plate having an opening therein to register with the opening in thetop when the plate has reached its limit of movement in the oppositedirection.

In witness whereof, I have hereunto affixed my signature.

DANIEL W. LAYMAN.
